Very interesting..... I started reloading for a .264 Mag in a 26" Finnbear. This was late '60s and did not have a lot of rifles back then. I wanted to shoot 140G. Nosler Partitions and had to load them. Hunted all over with that rifle and shot everything from Antelope
to bears in the Yukon and Alaska. Moose, Caribou, Fannin Sheep and a number of Mulies out West . One Elk around Thermopolis. The .264 is a good killer with the partitions. Never loaded anything else.

Never shot a whitetail as I hunt in Northern , Wi.......but a couple times I had that long open shot and wished for the Sako. The .264 got me started reloading... and I load for many cartridges now,but I hate reloading now . When I find a good shooting commercial load I use that.

The .264 is best when used in a 26" BBL. Prolly mentioned already. The short barreled Westerners don't do it.
